Hi Johannes, The BW tracking feature in mac80211 is causing connection problems and operating mode/bw problems when switching b/w modes and bw's in AP. For Eg. Initially if AP is operating in VHT-80MHz, and then we changed in to HT-40MHz, mac80211 cannot handle it because the VHT capability is mismatched b/w stored info (ifmgd->flags). I have tried your DISABLE_BW_TRACK patch, that helps making the connection but it doesn't update the chipset causing issues. Ideally we should be able to handle all the config changes right? -- Thanks, Regards, Chaitanya T K. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
